Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed August 1. 1907. Serial No. 386.630.

To all whom it may concern:

Be it known that I, EDMUND B. DIKEMAN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Combination-Tools; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in combination tools. I

The object of the invention is to provide a useful combination toolwhich will be simple, strong and durable, and which embodies in itsconstruction a wrench, hand-vise, hammer and screw driver.

WVith this object in view, the invention consists of certain novelfeatures of construc tion, combination and arrangement of parts as willbe more fully described and particularly pointed out in the appendedclaims.

In the accompanying drawings, Figure 1 is a side view of a toolconstructed in accord ance with the invention, parts of the same beingshown in section; Fig. 2 is a view of one edge of the tool; Fig. 3 is avertical cross sectional view on the line 33 of Fig. 1, looking in thedirection of the arrow, Fig. 4 is a detail sectional view on the line4-4 of Fig. 1; Fig. 5 is a side view of the tool showing a modified formof adjusting mechanism for the jaws; Fig. 6 is a detail sectional viewon the line 66 of Fig. 5; and Fig. 7 is a detail sectional view on theline 7-7 of Fig. 5.

Referring more particularly to the drawing, 1 denotes the tool, whichconsists of a pair of jaws, 2 and 3. The jaw 2 has on its inner side anapertured lug, 4, which is adapted to be engaged with a pair ofapertured lugs, or ears, 5, formed on the inner side of the jaw, 3.Through the apertures of the lugs 4 and 5 is arranged a pivot pin, 6,whereby the jaws 2 and 3 are pivotally connected together. On theopposing inner faces of the outer ends of the jaws, 2 and 3, is formed aseries of teeth, 7, whereby said jaws may be engaged with a nut or otherobject.

On the outer side of the jaw, 2, and preferably diametrically oppositeto its ivotal connection, is a hammer head, 8, on w 'ch is formed aclaw, 9. The jaw 2 has formed on its outer side or ed e a strengtheningrib, 10.

The inner end 0 the jaw 2 is extended to form a handle 11, in whichadjacent to its end, is formed a tapered slot, 12. In the inner side ofthe end of the handle 11 is formed a tapered, dovetailed recess, 13,

with which is adapted to be engaged a screw driver bit, 14. In the innerside of the jaw 2, between the handle portion and the pivotal connectionof said jaw, is formed a recess, 15, in which is arranged a transversepivot pin, 16, which extends through the jaw, as shown.

The jaw 3 is provided on its outer edge with a strengthening rib, 17,and on the inner end of the jaw is formed a flat, apertured extension,18, in which is loosely mounted a thimble nut, 19, which is adapted tobe engaged with an adjusting screw or bolt, 20, on the inner end ofwhich is formed a flat, circular head, 21, having an aperture throughwhich the pin 16 is passed, thereby pivotallyconnecting the bolt 20 withthe jaw 2. The thimble nut 19 is provided on its inner end with a milledhead, 22, in the edge of which is formed a series of radially disposedsockets or recesses, 23, adapted to receive a suitable instrument toassist in the turning of the nut. The outer end of the thimble nut 19 isreduced and threaded to receive a securing nut 24, by means of which thethimble nut 19 is retained in proper posi tion in the aperture of theextended end of the jaw, 3, and which is adapted to be loosely turned toscrew or unscrew the same on or off the bolt 20, which operation opensor closes the toothed ends of the jaws 2 and 3, and holds the same inany desired position, thus providing for the use of the same as anadjustable wrench or as a hand-vise.

In Fig. 5 of the drawings is shown a modified form of jaw adjustingmechanism, said mechanism being shown in this instance as consisting ofan adjusting bar, 24, having on its inner end a flattened aperture, 25,which is adapted to be pivotally connected to the jaw 2 by means of thepivot pin, 16, in the same manner as described in connection withthe'bolt, 20. The adjusting bar, 24, is provided on two of its oppositesides with a series of ratchet teeth 26.

In the inner end of the jaw 3 as shown in Figs. 5, 6 and 7 of thedrawings, is formed a transversely disposed hole, 27, which isintersected by a transversely disposed slot or passage, nect withlongitudinally disposed grooves or 28, the opposite ends of whichconchannels, 29, formed in the opposite side edges of the end of thejaw, as 0 early shown in Figs. 5 and 7 of the drawings.

Pivotally mounted in the grooves or channels 29 are pawls or dogs 30, onthe inner ends of which is formed a beveled tooth, 31. The teeth 31 areadapted to engage the teeth 26 of the adjusting bar, 24, which isadapted to work through the hole 27 in the jaw and serve to lock saidbar and thus hold the jaws 2 and 3 in their adjusted position. In theouter end of the jaw 3 is formed a trans versely disposed hole 32, whichcommunicates at its outer ends with the channels 29,

in which are pivoted the pawls, 30. In the passage 32 is disposed acoiled spring 33, the opposite ends of which are adapted to bear againstthe inner sides of the outer ends of the pawls 30, thereby yieldinglyholding-the inner ends of'the same in engagement with the teeth of theadjusting bar, 24.

The holding mechanism shown in connection with Figs. 5, 6 and 7 of thedrawings, provides for the quick adjustment of the jaw.

Having thus fully described my invention, whatI claim as new and desireto secure by Letters-Patent, is:

1. In a combination tool of the character described, a main orstationary jaw having a handle, a strengthening rib on the outer side ofsaid jaw, an adjustable jaw pivotally connected to said main jaw andcoacting therewith-to'form a vise, a strengthening rib on the outer sideof said adjustable jaw,

an adjustable bar pivotally mounted in said main jaw, an adjustablemechanism carried by said adjustable jaw to engage said adjust ing bar,and means to removably secure said adjusting mechanism in operativeposition, substantially as described.

2. A combination tool comprising a pair of jaws having on their'innersides apertured connecting lugs, a pivot pin arranged through said lugswhereby said jaws are ivotally connected together, an adjustingboltpivotally mounted on the inner side of one of said jaws, a thimblenut loosely mounted in the adjacent end of the opposite jaw, anoperating head formed on the inner end of said thimble nut, a securingnut adapted to be screwed onto the outer end of said thimble nut to holdthe same in place when the latter is screwed on or oif said adjustingbolt to open or close the jaws of the wrench, substantially asdescribed.

3. In combination with a tool of the character described, a main orstationary jaw having an integral handle, a strengthening rib on theouter side of said jaw, an apertured pivot lug on the inner side of thesame, an adjustable jaw, a'strengthening rib on the outer side of saidjaw, an apertured pivot lug on the inner side of the same to engage thepivot lug on said main jaw, a pivot pin arranged through said lugswhereby said jaws are pivotally connected together, a threaded adjustingbolt pivotally mounted in said main jaw, a thimble nut loosely mountedin said adjustable jaw, interior threads formed in one end of said nutto engage the threads on said bolt, exterior screw threads on the outerend of said nut, and a securing nut adapted to be screwed onto thethreaded outer end of said thimble nut whereby the same is held in anoperative position in said adjustable jaw, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
